Does anyone know of any software, android app or PC, for pulsating the ABS modules on GM vehicles, specifically the J1850 protocols (not CAN). There's FORScan, but it's support is limited to Ford vehicles. I changed the brake lines out, and have a pressure bleeder but need a way to pulsate the ABS to force the air out. And yes I've heard of the poor man's way of skidding on a dirt road. That is not a valid fix in my book.
